Cupcake Z Stage Assembly

This page is part of the Cupcake CNC build sequence.

For this you will need:

  • 16 M3x16 bolts
  • 16 M3 nuts
  • 4 Z Stage rod holding guides (U-shaped pieces of wood)

Attach the wooden Z Stage guides


NOTE: If your threaded rods aren't exactly straight, you may need to sand the insides of the Z stage down a bit where the nuts fit in. Sometimes you may also have to sand the inner parts of the wooden "U"s.

  1. Use your fingers to connect the wooden bracket to the top of the Z Stage with 4 M3 bolts and nuts.
  2. Use the 2.5mm Allen key to tighten them up. Be careful! In theory you could tighten it so much the acrylic would crack. We haven't done it yet, but it's theoretically possible so no air powered super-powerful drive bits here!
  3. Repeat for each corner!

NOTE: In newer batches the wooden brackets are U-shaped (not O-shaped) and should be mounted outwards. This makes it a lot easier to reposition and remove the platform without having to remove the Z-axis threaded rods.

Put your Z-stage on inside your MakerBot


Pick up the Z-stage and put it in the body. You'll want to screw the free nuts on the Z-stage rods down so you have enough room to maneuver.


The U of the Z stage opens to the front and the U of the Z Guides go to the sides now.
